Aluminum rolling direction 180 degrees bend cracking reasons 1. bend parallel edges and aluminum, it is easy to crack sales molds for aluminum factory in Jinan, the bending direction to turn 90 degrees. 2.180 degrees bending angle too die for Spot aluminum manufacturers, is greater than the minimum bend radius, usually bend radius of 1.5 times the thickness. 3. Materials reason, some manufacturers use aluminum alloys of aluminum, aluminum aluminum toughness no good, easy to crack. 4. thick sheet thickness, bend 180 degrees beyond the limit of the material is bent. 5. plate bending cracks, generally high phosphorus content of aluminum means the processing of aluminum and aluminum alloy plate-type material. aluminum alloy also can be divided into cold-rolled and hot-rolled, the main difference is the difference between the anodic oxidation of hot-rolled aluminum sheet can be anodized. Different cold rolled and hot-rolled aluminum uses aluminum, cold rolled aluminum sheet used for mold class, hot-rolled aluminum pull for stamping . extension due to the different aspects of the same material production process, its physical properties vary greatly aluminum is also known as plastic forming, aluminum during deformation by the force and deformation mode (stress - strain state) is divided into: casting, forging, extrusion, spinning, drawing, rolling, forming (cold, deep drawing) and other processing methods. Jinan spot aluminum molds for manufacturers, rolls aluminum molds for aluminum from Jinan Heshun Aluminum Co., Ltd. available. Jinan Heshun Aluminum Co. (www.jnhsly.com) Shandong Jinan, aluminum products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Aluminum leadership in cis with the staff warmly welcome all inquiries negotiations to create a better future for aluminum rolls.
